ontouch和的onclick上不工作

Question

一個TextView看看下面的代碼... 我設置上的TextView和ontouch監聽器，但他們都不是工作的onclick聽衆......

似乎什麼成爲問題> ....？

AlertDialog.Builder builder; 
    AlertDialog a; 
    TextView text,txtNewUser ; 
    ImageView image; 
    View layout; 
    Button ok; 
    String pswrd; 
    LayoutInflater inflater; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     final Context mContext = this; 
     Dialog dialog = new Dialog(mContext); 
     inflater = (LayoutInflater) mContext 
       .getSystemService(LAYOUT_INFLATER_SERVICE); 
     ok = (Button) findViewById(R.id.buttonOK); 

     dialog.setContentView(R.layout.custom_dialog_private_space); 
     dialog.setTitle("Password"); 
     dialog.setCancelable(true); 
     layout = inflater.inflate(R.layout.custom_dialog_private_space, 
       (ViewGroup) findViewById(R.id.layout)); 
     text = (TextView) dialog.findViewById(R.id.tvDesc); 
     txtNewUser = (TextView) dialog.findViewById(R.id.tvNewUser); 

     image = (ImageView) layout.findViewById(R.id.image); 
     image.setImageResource(R.drawable.lock_symbol_android); 

     builder = new AlertDialog.Builder(mContext); 
     builder.setView(layout); 

     a = builder.create(); 
     a.show(); 

     txtNewUser.setOnTouchListener(new OnTouchListener() { 

      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       // TODO Auto-generated method stub 
       if(event.getAction() == MotionEvent.ACTION_UP) 
       Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show(); 
       Log.v("AS", "Clicked"); 
    return true; 

      } 
     }); 

txtNewUser.setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show(); 
     Log.v("AS", "Clicked"); 
    } 
}); 
    } 

這裏的TextView從對話框佈局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:id="@+id/layout" > 

<TextView android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/tvNewUser" 
    android:text="New User?" 
    android:layout_gravity="top|left" 
    android:clickable="true" 

    /> 

    <ImageView 
     android:id="@+id/image" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     /> 

    <TextView 
     android:id="@+id/tvDesc" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:text="Enter password" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     /> 



    <EditText 
     android:id="@+id/etPassword" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:ems="100" 
     android:inputType="textPassword" > 


    </EditText> 

    <Button 
     android:id="@+id/buttonOK" 
     android:layout_width="100dp" 
     android:layout_gravity="center" 
     android:layout_height="fill_parent" 
     android:text="OK" /> 

</LinearLayout>

1. 而不是使用過窗類
2. 返回false在觸碰聆聽者

3. 集contenet以您的主要活動

Answer 2

我想的XML代碼..你也應該返回

return super.onTouchEvent(event); 

從onTouch功能.. ，而不是true，因爲true意味着該事件被觸摸消耗，並且其他操作不會針對此事件調用。在這種情況下，onClick

Answer 3

在敬酒你寫單擊了這樣改變onTouch聽衆接觸，並在onTouch偵聽器返回false兩種情況：

public class HomePage extends Activity { 
    private TextView txtNewUser; 
    private Context mContext; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     mContext = getApplicationContext(); 
     txtNewUser = (TextView) findViewById(R.id.tvNewUser); 

     txtNewUser.setOnTouchListener(new OnTouchListener() { 

      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       // TODO Auto-generated method stub 
       if (event.getAction() == MotionEvent.ACTION_UP) 
        Toast.makeText(mContext, "Touched ", Toast.LENGTH_SHORT) 
          .show(); 
       Log.v("AS", "Touched"); 
       return false; 

      } 
     }); 

     txtNewUser.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show(); 
       Log.v("AS", "Clicked"); 
      } 
     }); 

    }

這是我用來做imageview的點擊方式：

public class Main extends Activity **implements OnClickListener** { 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 


    ImageView profile_btn=(ImageView) findViewById(R.id.x_Btn); 
    x_btn.setOnClickListener(this) ; 


    ImageView food_btn=(ImageView) findViewById(R.id.y_Btn); 

    ybtn.setOnClickListener(this); 
    } 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
     switch(v.getId()) 
    { 
    case R.id.x_Btn: 
      //do some thing;break; 
        case R.id.y_Btn: 
    //do some thing;break; 
        } 
    } 
}
